Software requirements analysis for an extended ASW model

The FFI-project 795 "New Frigates" is a support study for the project SMP6088 "New Norwegian Escort Vessels" under the direction of the Royal Norwegian Navy’s Materiél Command. The main purpose of the study will be to ensure that the acquisition of the frigates will be achieved within the framework defined by the System Segment Specification for the Integrated Weapon System. A part of this study aims at the operational capability and efficiency of an ASW force escorting a high value surface unit under the threat of a submarine utilising one or more torpedoes as its weapon. This involves simulating such an ASW force including both tactical and technological aspects. This document describes the requirements for such a simulation and will be input to the later stages of specification and development of the necessary tools for accomplishing this task. An underlying assumption in this document is that extensions to and integration of already in-house models will be utilised for these simulations. These models are OSCAR, LYBIN and USIM. Nevertheless, this document can also be studied for a more general overview of requirements for such simulations and used as basis for selecting simulation tools.
